FUNNEL.

Specification of Letters Patent.

Application filed August 23, 1912. Serial No. 716,672.

Patented Apr. 21,1914.

To all whom it may concern: 1

Be it known that I, BERTIE EARL VVALTER, a citizen of the United States, residing at Tulsa, in the county of Tulsa and State of 5 Oklahoma, have invented new and useful Improvements in Funnels, of which the following is a specification.

The invention relates to-funnels, and more particularly to the class of valves for funnels.

The primary object of the invention is the provision of a valve wherein the rod thereof is covered with a glass tube, the latter terminating in a spherical tip forming the valve proper for the closing of the neck of the funne I Another object of the invention is the provision of a valve for funnels which is simple in construction, reliable and efficient in its purpose, and inexpensive in manufacture.

With these and other objects in view the invention consists in the construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings, and

pointed out in the claim hereunto appended.

In the drawings: Figure 1 is a side elevation of a funnel constructed in accordance with the invention. Fig. 2 is a similar View looking toward the opposite side thereof. Fig. 3 is a vertical longitudinal sectional view through the funnel. Fig. 4 is a top planview thereof. Fig. 5 is a sectional view through the valve rod.

Similar reference characters indicate corresponding parts throughout the several views in the drawings.

Referring to the drawings by numerals the funnel comprises a tapering body 5, con

structed from glass, and is formed at its upper mouth edge at one point thereof with a pouring spout or lip 6, while the opposite smaller end of said body is formed with a neck 7 of asize to telescope withiIitlie mouth of a bottle or other receptacle, the said neck 7 being formed at its'inner end with a valve seat 8 to accommodate a, closure stopper or valve presently described.

Integral with the body 5 at a point diametrically opposite the spout or lip 6 is a.

handle 9, while provided at the mouth edge of the body directly above the said handle are spaced parallel ears 10., between which is arranged an operating lever 11, the same being connected to the ears 10, by means of a pivot 12 and interposed between the outer end of this lever 11 and the upper surface of the handle is a coiled expansion spring 13, the latter beingsuitably seated within the lever-and handle so as to avoid the displacement thereof, while detachably connected to the inner end of the lever 11 is the upper end of a valve rod 14, the same extending downwardly into the body 5 and has surrounding the same a glass sleeve or hous- .65 ing 15, the lower end ofwhich is enlarged to form a valve or stopper 16 adapted to engage in the seat 8 at the inner end of the neck 7 for the closing thereof and in this manner prevent the discharge of the contents of the body 5, of the funnel when filled. The glass sleeve or housing 15 covering the valve rod 14 will prevent the" valve rod 14 or the contents of the body 5 from becoming aflected when the contents contains acid.

The spring 13 serves to keep the inner valve or plug end 16 normally seated, and on de pressing the lever 11 the valve or plug end- 16 will be raised, so as to permit the discharge of the contents of the funnel. n '80 Suitably marked or otherwise formed on" the outer face of the body 5 of the funnel at diametrically opposite points are distinctive graduated scales 17 and 18 respectively, so

that different liquids may be accurately I measured when poured into the funnel, the scale 17 being the metric system, while the scale 18 is'an avoirdupois system, although the scale systems may be varied if desired.

- From the foregoing description, taken in' connection with the accompanying drawings, it is thought that the construction and operation of the invention will be clearly understood, and therefore, a more extended explanation has been omitted.

What is claimed is The combination with a glass funnel having a contracted neck forming a valve seat, of a rod working within the funnel, and a glass tubefixed to the rod throughout the length thereof for covering the same and formed with a glass ball terminal about the lower end of the rod to provide'a valve engageable with the said seat.

In testimony whereof I aflix my signature 105. in presence of two witnesses.
